high-purity calcium for the food industry in thailand
the food and beverage industry in thailand is a major exporter to global markets, requiring ingredients that meet the highest international standards for purity and safety. calcium carbonate has several food-grade applications, including as a calcium fortifier in products like soy milk and cereal, as an anti-caking agent in powdered mixes, and as a firming agent in canned vegetables. To serve this exacting market, a dedicated food-grade calcium grinding mill has been established in the saraburi province, near bangkok, in a facility that is audited and certified for food safety.
this is not a standard industrial operation. the entire plant is designed and operated to meet the rigorous requirements of food manufacturing. the calcium grinding mill is a specialized stainless steel system, designed for easy cleaning and to prevent any contamination. it operates at a capacity of three tonnes per hour, allowing for meticulous batch processing and traceability. the raw material is sourced from a select, high-purity deposit that is regularly tested for the absence of heavy metals, pesticides, and microbiological contaminants.
for food applications, the fineness of the calcium carbonate is matched to its specific use. this mill produces a range of food-grade products. for calcium fortification in beverages, an ultra-fine grade with a d97 of ten micrometres is required to ensure it remains suspended in the liquid and does not create a gritty mouthfeel. for use as an anti-caking agent in powdered spices or drink mixes, a slightly coarser grade of seventy-five micrometres is effective. the key across all grades is absolute purity and consistency, with the plant operating under strict hazard analysis and critical control point principles.
the production environment at this food-grade facility is immaculate. the grinding mill and all conveying and packaging equipment are enclosed and kept under positive pressure with filtered air to prevent any dust or contamination from entering. the facility is designed for thorough cleaning between product runs to prevent cross-contamination. a comprehensive on-site laboratory tests every batch not only for particle size but also for heavy metals, microbial counts, and other food safety parameters. each batch is fully traceable from the mine to the final packaged product, with certificates of analysis provided to food manufacturers.
this specialized calcium grinding mill plays a vital role in thailand's food export success. it provides a reliable, certified source of a critical food ingredient, allowing thai food and beverage companies to meet the strict requirements of their customers in japan, the united states, and europe. by adding this high level of value and safety assurance to a simple mineral, the plant demonstrates the advanced capabilities of thailand's food processing industry and the crucial role of specialized mineral processing in the global food supply chain.
